What's the emblem I see on the fender of your 427 vert? Did you buy some 60th anniversary badges and stick them on?

Looks that way. Id do the same. Nothing wrong with it. In fact, I run the "60th anniversary" center caps on my cup wheels on my 06 Z. They just look nice IMO and so do those badges.

They're the 60th anniversary badges from the commemorative ed.
I thought they looked at home on the collector 427 vert, so I added them. GM p/n

Why - yours blew up?? Oh wait, it apparently didn't.

Bye!

The real men here just ponied up and paid for the fix. These cars are bulletproof except for the exhaust valve guide, which can't be fixed.... Oh wait - it can be fixed.

I get so tired of the Nancy boys here.....

You speak for alot of us my friend

Yes it did blow up after I sold it! From what I heard, it was beat on pretty good.

I also had lots of other problems. The car was not reliable. I like to drive it other than to the shop for repairs..

The car, out the door, was $86K and you want me to pay to fix GM's mistakes???

Flame away...

Coach62

Yeah - and the IRS hard drives really did fail, your checks in the mail, I won't c....

Coach62

Man, I get tired of having to post the same crap over and over. The LS7, and the Z06 is pretty damned bulletproof other than the exhaust valve guides.

The oiling issues are not that common, and were primarily on cars that had modified suspensions and R comp tires on long, hard left turns. It was more a case of modifying the car in some areas and not beefing it up in others. Again - this is easy to fix and common knowledge.

I get tired of people blaming the cars for failing when the cars were modified in some areas, and not beefed up in others to compensate. Like the guy on here crying about his blown up LS7 when he put a cam in it without fixing the heads.

Coach62

Howie, here are my issues. 1. those of us that chose the newer revised GM LS7 valves respect the decision of those that went solid SS, but that respect doesn't seem to go both ways.

2. - The solid SS valve is cheaper, actually much cheaper. If it was in fact better - and cheaper - wouldn't GM have used it in the stock engine?

Actually it seems there are two oiling issues, or perhaps three.

1. The 8 quart sump on early cars (pre-2009). This was the racetrack high-G left turn failure mode. The subsequent larger sump, altho only a band aid, seems to solve that issue (the ideal fix would be a better dry sump system and better windage control in the block).

2. Bearing failures on late cars ('12 - '13). Could be related to a change in bearing material during that period, or --

3. -- could be related to a few issues of suspected oil pump bypass valve failure (stuck open... a QC issue).

I got the Vert 427 new when the C7s were sitting on the dealer floor. I would way rather have the C6 vert then the C7, Im faster, handle better and will not see 30,000 427 60th verts around EVER. I have a 5 yr warranty and drive it very spirited (3rd and 4 th gear are my friend, red line tells me when to shift. If I dont break it then most wount, only 7500 miles so far) ,so if it fails its gunna be under 5 years. Traded my 2012 GS for this car and just Love it.
Too bad its too late already for all the rest to see the light.

I would add that the late model bearing failures seem to occur at very low miles (less than 3000), so if you've made it far past that then that would seem to be a good thing.

Bearing failure reports always seem to indicate, if not a knock, then very low oil pressure at idle (14 PSI or less) at normal oil temps. Hard starting (slow to turn over during cranking) is another symptom. Personally I would religiously run oil samples on these cars until out of what seems to be the danger range (again, several thousand miles).

I gotta agree with your logic. Bought my 427 vert used with 6,300 mi on it. It now has over 13,000 miles on it. I don't baby it, but don't abuse it. I've found 3rd gear to be an amazing passing gear. Like you say -- I have the balance of the factory warranty, so why worry about engine issues. Its a hoot to drive and will easily outperform the C7s that are so common.

Dirty Howie

1. Has nothing to do with respect. I respect that you came to a different conclusion than me as to which valve to use. I went with the pros that I trust plus what I saw with my own eyes on the track.

2. You are presuming that GM is infallible and most of us don't believe that.

Thats great...some of us are going to trust the guys that actually build PROVEN race engines.

propain

Zing!

Dirty Howie

I did trust guys that build race engines. Do I need to list all the CF vendors that build race engines and use SS valves for you ??

Come on Howie. You know your Rabi is WCCH and you took the advice from them. Not that anything is wrong with that but they are merely the guys who do the head work FOR the vendors who do race engines.

Most of those vendors who you will name just take the advice of whatever WCCH says to run. I can tell you some reputable engine builders in my area who suggested SS valves. Others laugh and ask if I am part of this forum. Others have never even heard of this drama.

When I pressed a bit further why they recommended SS they said "That's what the head guy said to use" or even better "That's what most people are asking for". When I said I don't want to use SS valves most said "Smart move, we can put in anything you like" most suggested titanium or stock OEM valves.
